Probes - HQ Series

The HQ Series is MikroMasch well-established state-of-the-art manufacturing and quality control technology. HQ probes are distinguished by their high quality and repeatability of characteristics. In particular, the probes have very consistent tip shape and radius, cantilever stiffness and resonance frequency, and laser reflectivity even for uncoated cantilevers.

Radius of Curvature. The radius of curvature measures the sharpness of a particular probe. Typically, the sharper the curvature radius the more fragile a silicon tip is. Conversely, a larger curvature radius provides greater durability but reduces the benefits of a sharper tip. Achieving a consistent balance delivers reliable and accurate results. 94% of HQ probes have a radius of curvature between 7 and 10nm.

Tip Shape Factor. A higher value indicates a higher aspect ratio probe. A tighter range of values indicates a more consistent tip shape. Results of the tip shape factor tests show consistent and close grouping of data. Known tip shape ensures the accuracy of results. 92% of HQ probes have an aspect ratio between 1.4 and 1.8.
